HAY-PRESS- Specification of Letters Patent.

Patented Oct. 2 1, 1905.

Application filed September 14, 1904:. Serial No. 224,437.

tion is to provide an improved form of press operated by horse-power, inwhich positive operating means are provided for advancing and retractingthe plunger twice for each complete revolution of the sweep of thehorse.

proved tucker, by means of which the charges of hay or other materialmay be smoothly folded within the compression-chamber.

Another object of the invention is to provide improved means forregulating the size of the opening at the discharge end of thecornpression-chamber, so that the degree of compression may be varied atwill, both dimensions of the opening at the discharge end of thecompression-chamber varying simultaneously.

1n the attainment of the objects above mentioned I make use of the novelconstruction and combination of parts of a baling-press hereinafterfully described, shown in the accompanying drawings, and having thenovel features thereof specifically pointed out in the appended claims,it being understood that changes'in the form, proportions, and exactmode of assemblage of the elements exhibited may be made withoutdeparting from the spirit of the invention or sacrificing any of theadvantages thereof.

.1 n the accompanying drawings, Figure 1 is a side elevation of thepress with the sweep of the horsepower broken off to save space. Fig. isa plan view of the structure shown in Fig. 1. Fig. 3 is an end elevationof the press, taken from the left of Fig. 1. Fig. 4c is a detailed viewin perspective of the preferred form of plunger. Fig. 5 is a viewshowing the operation of the mechanism by which the movement of thepitman is imparted to the plunger. Fig. 6 is a detail view of themechanism operated by the sweep, the parts being shown in the positionoccupied at the end of the compressing movement of the pitman. Fig. 7 isa detail plan view of another device for guiding the pitman. Fig. 8 is acrosssectional view on-the line 8 8 of Fig. 7.

Referring to the drawings, in which corresponding parts are designatedby similar characters of reference, B designates the bed of the press,which consists of longitudinal timbers 1 1 and transverse pieces 2, 3,and 4, by means of which the longitudinal timbers are securelyconnected. At the forward end of the bed B a plate 5 is bolted orotherwise secured upon the timbers 1 1, and upon the plate 5 is rigidlymounted a hub 6, in which a pivot-pin 7, formed on the under side of acasting 8, rotates. The casting 8 supports the sweep 9 of thehorsepower, which is bolted on the top of the casting, and is disposedat right angles to the casting, as best seen in Fig. 2. The casting 8forms a rotary cross head, by means of which motion is imparted to thelevers presently to be described, which operate the pitman through whichmotion imparted to the plunger of the press. To hold the casting 8 andsweep 9 in proper relative position, a stay-rod 10 is fastened at oneend to the casting. as shown in Fig. 2, and at the other end is attachedto the sweep at a point near the free end thereof, the connection of thestay-rod with the sweep not being shown.

The hub 6 on the plate 5 has formed thereon a projection 11, which isdirected forward, as shown in Fig. 1, and in the end of the projection11 is secured a steel pin 12, which extends downward through a pivotedlever-arm 13 and enters the plate 5. The lever-arm 13 is pivotallyconnected at its free end with a connecting rod or link 14, which ispivotally connected at the other end to the pitman 15, by means of whichthe plunger of the press is operated. The lever-arm 13 may be straightor may be formed on a compound curve, as shown in Fig. 1; but in eithercase a rib 16 is provided on the upper surface of the leverarm forengagement with steel rollers 17, rotatably mounted upon cottered pins18, mounted in the ends of the casting 8.

At one side of the plate 5 a lateral projection 20 is formed and thesteel pin 21 is cast on the projection to form a pivot for the lever-arm22, which is provided on its upper surface with a curved rib 23 forengagement with the rollers 17 above mentioned. The lever-arms 13 and 22are connected by means of a link 24, secured by pivot-pins in the endsof the lever-arms.

When the sweep 9 revolves in the direction indicated by the arrow as,one of the rollers 17 will engage with the rib 16 on the leverarm 13 andswing the lever to the position indicated in Fig. 6, at which point theroller 17 will pass over the end of the rib 16 and the motion of thelever-arm in that direction will cease. Immediately after the cessationof movement of the arm 13 the other roller 17 will come into contactwith the rib 23 on the lever-arm 22, which is then in the position shownin Fig. 6. The movement of the sweep after the roller 17 engages the rib23 will force the arm 22 back to its solid-line position, and as thearms 13 and 22 are connected by means of the link 24: the arm 13 willalso be restored to its solid-line position. By the time the arms 22 and13 have reached their original position the roller 17 will pass out ofengagement with the rib 23 and soon afterward will contact with the rib16 and cause a repetition of the operations just described. It will thusbe seen that a half-revolution of the sweep 9 will cause the arms 13 and22 to move from their position in Fig. 2 to the position in Fig. 6 andthen to return to the original position. As the arm 13 is connected, bymeans of the connecting-bar 14, with the plunger-operating pitman 15,each complete swing of the arm 13 will cause a complete reciprocation ofthe pitman.

The pitman consists, preferably,'of an iron pipe 25, provided at theends with slotted heads 26 and 27, the former of which projects abovethe plane of the upper surface of the bed B of the press. Throughout thegreater portion of its length the pitman is covered by a shield or cover28, placed on top of the longitudinal timbers 1 1, and in order toprevent the strain imposed upon the pitman by the connecting-bar 1 1from drawing it into contact with one of the timbers 1 an arm 29 ispivotally mounted at one end of the transverse bar 4 and pivotallyconnected at its other end with the pitman-head 26. The arm 29 causesthe head 26 of the pitman to move in an arc whose radius is equal to thedistance between the pivots in the ends of the-bar 29, and in order toafford effective support for the pitmanhead 26 the curved track 30 isprovided on the bed of the press.

The structures thus described cause the pitman to move in a pathsufficiently straight for all practical purposes; but if it is desiredto cause the pitman to have a simple to-and-fro movement any of theordinary means for effecting such a movement may be substituted for thepivoted arm 29.

The pitman-head 27 extends beneath the frame F of the press proper andis pivotally connected with one arm of a bell-crank lever 31, supportedon a transverse shaft 32, which is mountedin the press-frame. The otherarm of the bell-crank 31 is disposed at an angle of about one hundredand twenty degrees to the arm connected with the pitman and is pivotallyconnected with two stout connecting bars 33, the other ends of which aremounted on a pin 34, connecting the members 35 and 36 of a toggle, bymeans of which the plunger P of the press is operated. The member 35 ofthe toggle is preferably composed of two bars riveted together, as shownin Fig. 2, and is pivotally connected with the plunger by means of a pin37. The member 36 of the toggle is also composed of two bars rivetedtogether; but at their lower ends the two bars are spread apart and aresupported upon a shaft 38, secured in bearings 39 on the press-frame.

The plunger P consists, preferably, of a block 40, supported on guidemembers 41, a horizontal top 42, and an upright tailpiece 14:, mountedon the top 42 and suitably braced. The toggle member 35 is connecteddirectly to the block 10 and the top 42. The top 42 and the tailpiece Mare slotted, as best seen in Fig. 4:, to permit the free movement of thetoggle in reciprocating the plunger. The plunger operates in acharging-chamber C and is provided at the sides of the block withnotches 45 for the passage of the springretainers, by means of which thecharges forced forward by the plunger are prevented from returning intothe charging -chamber. The springretainers consist, preferably, of flatsprings 46, provided at their free ends with triangular pieces of castiron 46, which project into the charging-chamber. At the end of thecharging-chamber and just above the spring-retainers is mounted atucker, which consists of a metal bar 47, preferably of quarter-roundcrosssection, which is supported by pivoted arms 18 and is normallydepressed by coiled springs 49 engaging projections 50 on the uppersurface of the bar 47. The springs 19 are held in place by brackets 51,supported upon one of the cross-timbers of the press-frame at the end ofthe chargingchamber.

Just behind the chargingchamber is the compression-chamber C, whichconsists in the preferred form of upper and lower sections 52 and 53,respectively, and has at its discharge end means for drawing the upperand lower sections together to vary the degree of compression of thematerial upon which the press operates.

The compression-regulating devices at the end of the chamber C consist,preferably, of upper links 5&, provided on either side of thecompression-chamber, lower links 55, levers 56, having cams 57 at theirinner ends, pressure-plates 58, with which said cams engage,

and means for securing the levers in adjusted position. The levers 56are pivotally connected with links 54 and 55, as shown in Fig. 3, andthe cams at the ends of the levers engage with suitably-formed surfaceson the exterior of the plates 58, which are supported by links 59,attached to the upper and lower sections of the compression-chamber.Each of the levers 56 is preferably provided at its outer end with aneye 60 for the reception of a rod by means of which the length of thelever may be increased and greater power obtained.

The fastening devices employed to secure the levers in adjusted positionconsist, preferably, of keepers 61, attached to the bottom of thecompression-chamber,and arms 62, pivoted to the levers 56 and providedat their lower ends with a plurality of openings for engagement with thekeepers 61.

From the foregoing description and an inspection of Fig. 4 it will beseen that when the levers 56 are depressed the links 54 and 55 will bothbe subjected to strain and the upper and lower sections of thecompressionchamber drawn together. At the same time the action of thecams at the ends of the levers upon the plates 58 will force theminward, and the discharge-opening at the end of the compression-chamberwill be reduced in height and width simultaneously.

The general operation of the press is similar to other pitman-operatedpresses, the material to be compressed being fed into thecharging-ehamber in any preferred manner and being forced forward by theplunger P, a-single charge being forced into the compression-chamber ateach reciprocation of the plunger. The travel of the plunger isindicated in Fig. 1, in which the plunger is in the retracted position,and in Fig. 5 in the advanced position, each advance of the plungerbeing produced by the extension of the toggle when the bell-crank lever31 is rocked upon its shaft 32 by the rearward movement of the pitman15.

Any preferred method of securing the ma:

terials compressed by the press to form bales may be employed, and asthe completion of the bales forms no part of the present invention themethod of doing so need not be described.

To insure a reciprocating movement of the pitman in an absolutelystraight direction, 1 have provided means, as indicated in Figs. 7 and8, wherein is shown a grooved guideroller 63, which is mounted within afork 64, carried by and projected in front of the pitman, the rollerbeing mounted to rotate upon a vertical axis 65, which projects abovethe fork and has the rear end of the connecting rod or link 14 connectedto the upper end thereof. This guide-roller 63 works between and engagesa guideway or tracks formed by blocks 66, secured to the inner faces ofthe respective sills 1 by suitable fastenings 67, preferably bolts. Bythis arrangement the roller 63 of course travels in a straight directionin the guideway or between the two tracks 66, thereby compelling thepitman 25 to also opcrate in a straight direction without lateral swing.
